Description
Technical Field
[0001] This application relates to the field of automotive seat belt technology, and more particularly to assembly equipment for automotive seat belts. Background Technology
[0002] Car seat belts are a crucial component of automotive safety equipment. Common car seat belts typically consist of webbing, a retractor, guide plates, D-rings, and locking latches. In the event of an accident, car seat belts can quickly secure a person to their seat, preventing them from being thrown out due to the car's high-speed inertia and avoiding impacts with the steering wheel or other objects.
[0003] Typically, the housing of a retractor forms two spaced-apart mounting holes. The guide plate includes two spaced-apart mounting arms and a connecting portion between the two mounting arms. Each mounting arm has a locking post on its opposite side away from the connecting portion. The guide plate is assembled to the housing by inserting the locking posts of the two mounting arms into the two mounting holes. Currently, during assembly, the guide plate is first assembled to the housing, and then the webbing is passed through the radial insertion channel of the retractor's winding shaft and the locking channel formed by the connecting portion of the guide plate. Since the guide plate can rotate relative to the housing around the locking posts after assembly, the position of the locking channel is in a floating state. Therefore, a limiting structure is usually required to limit the position of the guide plate; otherwise, the webbing direction needs to be adjusted according to the position of the locking channel. This significantly complicates the overall structure and increases equipment costs. Summary of the Invention

[0036] refer to Figures 1 to 13An assembly apparatus for automotive seat belts according to a preferred embodiment of this application will be described in detail below. The assembly apparatus is used to mount a guide plate 120 and a webbing 130 onto a retractor 110. The retractor 110 includes a housing 111 and a retractor shaft 112 connected to a coil spring. The housing 111 has two oppositely spaced insertion holes 11101, and the retractor shaft 112 is rotatably mounted to the housing 111. The retractor shaft 112 forms a radially penetrating insertion channel 11201, which includes a receiving hole 112011 and a connecting hole 112012 communicating with the receiving hole 112011. A cross-section is taken along the direction extending from the receiving hole 112011 to the connecting hole 112012. The distance between the two opposite sidewalls on the cross-section of the receiving hole 112011 is greater than the distance between the two opposite sidewalls on the cross-section of the connecting hole 112012. A clip 140 is partially inserted into the connecting hole 112012 through the receiving hole 112011, and the housing 111 is partially located in the direction in which the clip 140 is rotated by the winding shaft 112, which is driven by the elastic action of the coil spring, to abut against the clip 140, so as to prevent the winding shaft 112 and the housing 111 from rotating relative to each other. The guide plate 120 includes two spaced-apart mounting arms 121 and a connecting portion 122 connecting the two mounting arms 121. The connecting portion 122 of the guide plate 120 has a locking channel 12201.

The horizontal drive group 321 and the extraction body 31 are driven by the vertical drive group 322 to rise and fall, so that the extraction body 31 can be kept at the same height as the clip 140, which facilitates the subsequent extraction of the clip 140.
[0049] Furthermore, the drive unit 32 also includes a longitudinal drive group 323, which is installed on the main body 10 of the device. The vertical drive group 322 is installed on the longitudinal drive group 323. The vertical drive group 322, the horizontal drive group 321 and the extraction body 31 are driven by the longitudinal drive group 323 to move the extraction body 31 to or away from the vertical surface where the insertion channel 11201 extends, so as to facilitate the subsequent extraction of the clip 140.
[0050] Preferably, the lateral drive group 321, the vertical drive group 322, and the longitudinal drive group 323 are all implemented with respect to, but not limited to, cylinders.
[0051] It is worth mentioning that the portion of the placement platform 21 that forms the contact plane 2101 forms a clearance groove 2103 that communicates with the arc groove 2102. The clearance groove 2103 allows the clip 140 to pass through, facilitating the extraction operation.

[0054] refer to Figure 1 as well as Figures 8 to 10 The assembly equipment for automotive seat belts includes a belt feeding mechanism 50 located on the side of the placement platform 21 away from the mounting body 41. The webbing 130 is conveyed by the belt feeding mechanism 50 and moved toward the contact plane 2101 of the placement platform 21 to pass through the insertion channel 11201 of the retractor 110 carried by the placement platform 21 and the locking channel 12201 of the guide plate 120 carried by the mounting body 41, so as to realize the assembly of the webbing 130 with the retractor 110 and the guide plate 120.
[0055] Preferably, the tape feeding mechanism 50 includes a tape feeding platform 51 and a tape feeding unit 52. The tape feeding platform 51 is located on the side of the placement platform 21 away from the placement body 41 and corresponds to the placement platform 21. The tape feeding platform 51 is used to carry the webbing 130. The tape feeding unit 52 includes a first tape feeding component 521, which is installed on the tape feeding platform 51.

[0057] Preferably, a through hole 5101 is formed in the middle of the feeding platform 51, and the first feeding roller 5211 is partially placed in the through hole 5101 to make the whole compact, and by applying force to the webbing 130 in the middle of the feeding platform 51, the possibility of the webbing 130 wrinkling is reduced.
[0058] Furthermore, the first belt feeding component 521 also includes a drive unit 5212, wherein the first belt feeding roller 5211 is mounted on the drive unit 5212 and is driven to rotate by the drive unit 5212.
[0059] In one embodiment, the drive unit 5212 is implemented with respect to, but not limited to, an electric motor.
[0060] Furthermore, the tape feeding unit 52 also includes a second tape feeding component 522, which is at least partially positioned above the tape feeding platform 51. The second tape feeding component 522 and the first tape feeding component 521 work together to convey the webbing 130.
[0061] Preferably, the second feeding member 522 includes a second feeding assembly 5221, which includes a mounting plate 52211 and a second feeding roller 52212.

The second feeding roller 52212 is driven to rise and fall to separate from or come into contact with the portion of the webbing 130 whose belt portion 131 is positioned above the first feeding roller 5211. Based on the second feed roller 52212 descending to contact the portion of the webbing 130 whose belt portion 131 is positioned above the first feed roller 5211, if the first feed roller 5211 pauses rotation, the second feed roller 52212 and the first feed roller 5211 cooperate to fix the belt portion 131, so as to prevent the belt portion 131 from continuing to move before the clamp 140 extraction operation is completed, and to ensure that the subsequent webbing 130 smoothly overlaps the placement platform 21; if the first feed roller 5211 rotates, the second feed roller 52212 is driven to rotate by the belt portion 131 conveyed by the first feed member 521, and the second feed roller 52212 and the first feed roller 5211 cooperate to convey the webbing 130. In this way, the first tape feeding component 521 and the second tape feeding component 522 cooperate with each other to control the transmission of the webbing 130 to match the extraction operation of the clip 140 and ensure that the webbing 130 can be transmitted stably.

The belt testing mechanism 60 is used to detect whether the webbing 130 has partially moved between the second belt feeding roller 52212 and the first belt feeding roller 5211. The belt testing mechanism 60 is communicatively connected to a controller, and the lifting assembly 5222 is controllably connected to the controller. The controller selectively controls the operation of the lifting assembly 5222 based on feedback from the belt testing mechanism 60 to automatically control the lifting and lowering of the second belt feeding assembly 5221.
[0065] Specifically, when the measuring mechanism 60 detects the webbing 130, the controller controls the lifting unit 5222 to operate, and the second feeding roller 52212 is driven by the lifting unit 5222 to move down to contact the webbing 130.
[0066] Preferably, there are two measuring mechanisms 60, which are arranged at intervals on both sides of the second feeding roller 52212, so that the two measuring mechanisms 60 can detect the webbing 130 at the same time, thereby improving the detection accuracy.

When the placement body 41 is lowered so that its upper surface is offset from the contact plane 2101 and kept below the contact plane 2101, it facilitates the worker to place the guide plate 120 onto the placement body 41 and avoids obstacles during the installation operation of the guide plate 120.
[0071] Further, the placement body 41 includes a first portion 411 and a second portion 412. The first portion 411 is mounted on the vertical moving force assembly 421 and is driven to rise and fall by the vertical moving force assembly 421. When the first portion 411 is driven to rise by the vertical moving force assembly 421 so that its upper surface is kept at the same level as the contact plane 2101 of the placement platform 21, the first portion 411 is used to support the portion of the belt 131 that is moved away from the placement platform 21. The placement groove 4101 and the placement notch 4102 are both formed in the second portion 412. The position adjustment assembly 42 further includes a longitudinal movement force assembly 422, which is installed on the first part 411. The second part 412 is installed on the longitudinal movement force assembly 422 and is driven by the longitudinal movement force assembly 422 to translate along a horizontal direction perpendicular to the conveying direction of the webbing 130 to correspond to or offset from the first part 411, so as to facilitate the placement operation of the guide plate 120 when the second part 412 is offset from the first part 411.
[0072] refer to Figure 1 and Figure 11 Furthermore, the assembly equipment for automotive seat belts also includes an installation mechanism 70, which is disposed on the same side as the mounting body 41.

[0073] It is worth mentioning that the placement platform 21 forms at least one anti-rotation part 211. The anti-rotation part 211 is placed outside the housing 111 of the retractor 110 carried by the placement platform 21, and the anti-rotation part 211 is located on the rotation trajectory of the housing 111 relative to the fixed retractor shaft 112 when the clamp 140 is pulled out, so as to prevent the housing 111 from rotating and play a role in fixing the housing 111. In this way, after the mounting mechanism 70 assembles the guide plate 120 into the housing 111, the guide plate 120's groove 12201 remains in the direction extending from the contact plane 2101 toward the retractor 110 carried by the placement platform 21. This keeps the movement trajectory of the webbing 130 unchanged, making it easier to assemble the webbing 130 into place later.
[0074] The installation mechanism 70 includes an insertion unit 71, which is disposed on the same side as the mounting body 41. The insertion unit 71 can be driven to grab the guide plate 120, which is carried by the mounting body 41 and is inserted into the belt 131, and assemble it into the housing 111.
[0075] The installation mechanism 70 also includes an insertion power unit 72, which is installed on the equipment body 10. The insertion unit 71 is installed on the insertion power unit 72 and is driven by the insertion power unit 72 to move sequentially toward the placement body 41 and the placement platform 21 in order to perform the assembly operation of the guide plate 120.
[0076] Preferably, the insertion power unit 72 includes a lifting power component 721 and a lateral movement force component 722. The lifting power component 721 is connected to the lateral movement force component 722. Either the lifting power component 721 or the lateral movement force component 722 is connected to the main body 10, while the other is equipped with the insertion unit 71. The insertion unit 71 can be driven by the lifting power component 721 to be raised and lowered to maintain the same height as the guide plate 120 carried by the placement main body 41 or to maintain the same height as the portion of the retractor 110 carried by the placement platform 21 that forms the insertion hole 11101, so as to clamp or install the guide plate 120. The insertion unit 71 and the housing 111 of the retractor 110, which is supported by the placement platform 21, are held on the same vertical plane. The insertion unit 71 can be moved by the lateral movement force member 722 along a direction parallel to the conveying direction of the webbing 130 to move closer to or away from the placement platform 21. In this way, the lifting force member 721 and the lateral movement force member 722 work together to control the position of the insertion unit 71 so that the installation operation of the guide plate 120 can be carried out.
[0077] Preferably, the insert unit 71 is installed on the lateral movement force member 722, and the insert unit 71 and the lateral movement force member 722 as a whole are driven to rise and fall by the lifting power member 721.
[0078] Preferably, both the lifting power component 721 and the lateral movement power component 722 are implemented with respect to, but not limited to, telescopic cylinders.
[0079] Preferably, the insertion unit 71 includes an insertion assembly 711 and a connector 712. The insertion assembly 711 includes a primary insertion component 7111 and a secondary insertion component 7112. The connector 712 is mounted on the insertion power unit 72. Both the primary insertion component 7111 and the secondary insertion component 7112 are mounted on the connector 712 and are driven by the insertion power unit 72 to approach the guide plate 120 carried by the placement body 41 and the retractor 110 carried by the placement platform 21. After the primary insertion component 7111 is driven by the insertion power unit 72 to approach the guide plate 120, the primary insertion component 7111 clamps the guide plate 120 by applying opposing forces to the two mounting arms 121. The initial mounting component 7111, which holds the guide plate 120, is driven by the insertion power unit 72 to approach the placement platform 21, so that the guide plate 120 is positioned between the portions of the housing 111 that form the two insertion holes 11101, with each of the two mounting arms 121 having a locking post 1211 corresponding to one of the two insertion holes 11101, thus achieving initial installation of the guide plate 120. When the two locking posts 1211 of the two mounting arms 121 correspond to the two insertion holes 11101, the remounting component 7112 applies opposing forces to the two mounting arms 121, causing each of the two locking posts 1211 of the two mounting arms 121 to pass through the insertion hole 11101 and engage with the corresponding insertion hole 11101, thereby assembling the guide plate 120 into place.
[0080] Preferably, both the initial assembly component 7111 and the reassembly component 7112 are implemented with, but are not limited to, clamping cylinders.
[0081] refer to Figure 1 , Figure 12 and Figure 13 The assembly equipment for automotive seat belts includes a belt conveyor mechanism 80, which includes a belt conveyor platform 81. The belt conveyor platform 81 is mounted on the equipment body 10 and located on the side of the placement body 41 away from the placement platform 21. The webbing 130's tape portion 131 passes through the insertion channel 11201 of the retractor 110 carried by the placement platform 21 and the locking channel 12201 of the guide plate 120 before moving to the belt conveyor platform 81.
[0082] The belt conveyor mechanism 80 includes a belt conveyor unit 82, which includes a first belt conveyor assembly 821. The first belt conveyor assembly 821 is mounted on the belt conveyor platform 81. The first belt conveyor assembly 821 is used to drive the belt portion 131 of the webbing 130 to move toward the placement platform 21 in the direction extending toward the belt conveyor platform 81, so that the pin 132 moves toward the receiving hole 112011 of the insertion channel 11201.
[0083] It is worth mentioning that when the belt portion 131 of the webbing 130 is moved by the first belt conveyor assembly 821, the second belt feeding assembly 5221 is driven to rise by the lifting assembly 5222 so that the second belt feeding roller 52212 is separated from the belt portion 131 of the webbing 130. This is to prevent the distance between the second belt feeding roller 52212 and the first belt feeding roller 5211 from being too small, which would affect the movement of the pin 132 of the webbing 130 and affect the assembly of the webbing 130.
[0084] Furthermore, the first conveyor assembly 821 includes a first conveyor roller 8211, which is rotatably mounted on the conveyor platform 81. The rotation direction of the first conveyor roller 8211 is the same as the rotation direction of the first feed roller 5211. The first conveyor roller 8211 rotates to drive the belt portion 131 of the webbing 130 to move toward the placement platform 21 in the direction extending toward the conveyor platform 81.
[0085] Furthermore, the first belt conveyor assembly 821 also includes a belt rotating unit 8212, wherein the first belt conveyor roller 8211 is mounted on the belt rotating unit 8212 and is driven to rotate by the belt rotating unit 8212.
[0086] Preferably, the rotating unit 8212 is implemented with respect to, but not limited to, a motor.
[0087] The conveyor unit 82 further includes a second conveyor assembly 822, which includes a second conveyor roller 8221. The second conveyor roller 8221 is rotatably disposed above the first conveyor roller 8211, and the rotation direction of the second conveyor roller 8221 is opposite to the rotation direction of the first conveyor roller 8211. The second conveyor roller 8221 is driven to rise and fall to separate from or come into contact with the portion of the webbing 130 that is positioned on the first conveyor roller 8211. When the second conveyor roller 8221 descends and comes into contact with the portion of the webbing 130 that is positioned on the first conveyor roller 8211, the second conveyor roller 8221 is driven to rotate by the webbing 131 driven by the first conveyor roller 8211. The second conveyor roller 8221 cooperates with the first conveyor roller 8211 to collaboratively convey the webbing 130, ensuring that the webbing 130 can be conveyed smoothly.
[0088] The second conveyor belt assembly 822 further includes a lifting belt transfer group 8222, which is installed on the equipment body 10. The second conveyor belt roller 8221 is rotatably installed on the lifting belt transfer group 8222 and is driven by the lifting belt transfer group 8222 to move up and down.
[0089] Preferably, the lifting belt shifting assembly 8222 is implemented with respect to, but not limited to, a telescopic cylinder.
[0090] refer to Figure 7 It is worth mentioning that the assembly equipment for automotive seat belts includes an installation detection mechanism 90, which includes an installation detection component 91. The installation detection component 91 is located on the side of the placement platform 21 near the belt feeding platform 51, and can correspond to the placement platform 21 to radiate a signal to the receiving hole 112011 of the retractor 110 carried by the placement platform 21 to detect whether the pin 132 is engaged in the receiving hole 112011. The installation detection component 91 is communicatively connected to the controller, and the alarm or the belt conveyor 8212 of the first belt conveyor assembly 821 is controllably connected to the controller. The controller selectively controls the operation of the alarm or the belt conveyor 8212 based on the feedback from the installation detection component 91.
[0091] Preferably, the positioning detection element 91 is implemented with respect to, but not limited to, a distance sensor.
[0092] Specifically, the positioning detection element 91, implemented as a distance sensor, radiates a signal to the location of the receiving hole 112011 to perform distance detection. The positioning detection element 91 feeds back to the controller. If the controller determines that the distance data is within a predetermined range, it indicates that the pin 132 is properly assembled, and the controller controls the alarm or the belt conveyor 8212 to stop operating. If the controller determines that the distance data is outside the predetermined range, it indicates that the pin 132 is not properly assembled, and the controller controls the alarm or the belt conveyor 8212 to operate to provide a warning or the belt conveyor 8212 drives the first conveyor roller 8211 to rotate so that the belt 131 continues to move.
[0093] Furthermore, the positioning detection mechanism 90 also includes a moving unit 92, which includes a lateral pushing group 921. The positioning detection component 91 is installed on the lateral pushing group 921 and is driven by the lateral pushing group 921 to extend toward or retract from the receiving hole 112011 when it corresponds to the retractor 110 carried by the placement platform 21, so that the positioning detection component 91 can perform close-range detection and increase the accuracy of detection.
[0094] Furthermore, the conveyor unit 92 also includes a vertical pushing group 922. The horizontal pushing group 921 is installed on the vertical pushing group 922 and is driven by the vertical pushing group 922 to remain on the same plane as the retractor 110 carried by the placement platform 21, so that the subsequent mounting detection element 91 moves towards the receiving hole 112011.
[0095] Preferably, the vertical pushing group 922 is installed on the longitudinal driving group 323. The vertical pushing group 922 is driven by the longitudinal driving group 323 to move the positioning detection element 91 connected thereto to or away from the vertical surface where the insertion hole 11101 of the retractor 110 carried by the placement platform 21 extends, so that the positioning detection element 91 can detect it subsequently.
[0096] Preferably, both the lateral pushing group 921 and the vertical pushing group 922 are implemented with respect to, but not limited to, telescopic cylinders.
